Notes:please connect the outdoor unit to the power,
then connect the indoor unit to the power,
otherwise,the failure code[95]may appear.
At this time,press the "self-check"button on the
wired controller for at least 10 senconds to delete
the failure code.(The machine's operation will
not be influenced by such a phenomenon)
